-# A simple mod for online player time and server status
+# A simple mod for tracking online player time and server status
 [中文简体](https://git.branulf.top/Branulf/ServerPlayerOnlineTracker/src/branch/master/README.md)
 
-### Includes functions:
-* Display /Record server online player time
-* Display server status
-* Show the server online player list
-* ~~Remove Herobrine in the game~~
+Note: This mod is not perfect and may have some bugs.
+### Features include:
+* Display/record server online player time
+* Show server status
+* Display a list of online players on the server
+* ~~Remove Herobrine from the game~~
 
 ### How to use:
-1. Install Fabric Loader and Fabric API
-2. Put the latest version of mods into the mods folder
-3. Automatically generate configuration files when starting the server for the first time
-4. Modify the web server port (default 60048), language (currently only supports zh_cn and en_us), automatic save time (default 300 seconds)
+1. Install Fabric Loader and Fabric API.
+2. Place the latest version of the mod into the mods folder.
+3. The configuration file will be generated automatically when starting the server for the first time.
+4. Modify the web server port (default 60048), language (currently only supports zh_cn and en_us), and automatic save interval (default 300 seconds).
+5. If external access is needed, ensure that the port is open.
 
-### API to get data:
-*(Maybe it can be used for robots?)*
-* Get the online player list of servers: [Server IP+configured port] +`/api/online-players`
+### API data retrieval:
+*(Maybe can be used for bots?)*
+* Get a list of online players on the server: [Server IP + configured port] + `/api/online-players`
 * Get server status: [Server IP + configured port] + `/api/server-status`
-* Get the server online player time: [Server IP+configured port] +`/api/stats`
-* Get the number of online players on the server: [Server IP+configured port] +`/api/player-count`
+* Get online player time on the server: [Server IP + configured port] + `/api/stats`
